{'InstanceMatchCriteria': 'open | targeted'}

Modifies a Capacity Reservation's capacity, instance eligibility, and the conditions under which it is to be released. You can't modify a Capacity Reservation's instance type, EBS optimization, platform, instance store settings, Availability Zone, or tenancy. If you need to modify any of these attributes, we recommend that you cancel the Capacity Reservation, and then create a new one with the required attributes. For more information, see Modify an active Capacity Reservation.

type CapacityReservationId

string

param CapacityReservationId

[REQUIRED]

The ID of the Capacity Reservation.

type InstanceCount

integer

param InstanceCount

The number of instances for which to reserve capacity. The number of instances can't be increased or decreased by more than 1000 in a single request.

type EndDate

datetime

param EndDate

The date and time at which the Capacity Reservation expires. When a Capacity Reservation expires, the reserved capacity is released and you can no longer launch instances into it. The Capacity Reservation's state changes to expired when it reaches its end date and time.

The Capacity Reservation is cancelled within an hour from the specified time. For example, if you specify 5/31/2019, 13:30:55, the Capacity Reservation is guaranteed to end between 13:30:55 and 14:30:55 on 5/31/2019.

You must provide an EndDate value if EndDateType is limited . Omit EndDate if EndDateType is unlimited .

type EndDateType

string

param EndDateType

Indicates the way in which the Capacity Reservation ends. A Capacity Reservation can have one of the following end types:

• unlimited - The Capacity Reservation remains active until you explicitly cancel it. Do not provide an EndDate value if EndDateType is unlimited .

• limited - The Capacity Reservation expires automatically at a specified date and time. You must provide an EndDate value if EndDateType is limited .

type Accept

boolean

param Accept

Reserved. Capacity Reservations you have created are accepted by default.

type DryRun

boolean

param DryRun

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

type AdditionalInfo

string

param AdditionalInfo

Reserved for future use.

type InstanceMatchCriteria

string

param InstanceMatchCriteria

The matching criteria (instance eligibility) that you want to use in the modified Capacity Reservation. If you change the instance eligibility of an existing Capacity Reservation from targeted to open , any running instances that match the attributes of the Capacity Reservation, have the CapacityReservationPreference set to open , and are not yet running in the Capacity Reservation, will automatically use the modified Capacity Reservation.

To modify the instance eligibility, the Capacity Reservation must be completely idle (zero usage).
